Abstract

Background: The aim of this study is to compare long-term health-related quality of life (HRQOL) and survival in metastatic NSCLC patients with (M+) and without (M−) a targetable driver mutation. Methods: An observational study was performed within the prospective SYMPRO-lung study (NL7897). HRQOL questionnaires were completed at baseline, 15 weeks, and 6 months. Generalized estimating equations (GEE) were used to assess clinically significant declines in HRQOL (>10 points) over time. Kaplan–Meier survival curves were plotted for both progression-free survival (PFS) and overall survival (OS). Results: 81 metastatic NSCLC patients were included (M+ patients; 16 (20%)). M+ patients had a significantly better global HRQOL (mean difference 12.8, ES 0.61), physical functioning (mean difference 13.4, ES 0.63), and less appetite loss (mean difference 23.1, ES 0.73) at 15 weeks of follow-up compared to M− patients. Patients with a clinically relevant decline in HRQOL at 6 months of follow-up had a significantly shorter PFS (5 months vs. 12 months, p-value < 0.001) and OS (11 months vs. 16 months, p-value 0.002). Conclusions: M− NSCLC patients have less favorable HRQOL over time compared to M+ patients. Furthermore, clinically relevant HRQOL declines over time were significantly associated with worse survival. HRQOL can therefore play an important role in in shaping patients’ expectations of their prognosis.
